Descrição geral

4-Fluorophthalic anhydride is a fluorinated building block commonly used in chemical synthesis for the preparation of polyimide, pesticides, herbicides, and fungicides. It can be synthesized by treating 4-chlorophthalic anhydride with potassium fluoride.

Aplicação

4-Fluorophthalic anhydride can be used as a reactant to prepare:
  • 4-amino substituted phthalimides applicable as potential fluorescent probes and fluorescent bioactive compounds.
  • 4,4′-bis(4-fluorophthalimido)diphenyl ether monomer, which is used in the synthesis of cardo polymers via nucleophilic substitution polymerization reaction.
  • Asymmetric polyimides by a solution polycondensation reaction.

In addition to possessing excellent chemical, mechanical, and thermal stability, polyimides and polyetherimides have excellent solubility in many solvents, which renders them suitable for membrane preparation. Two new monomers [a pentiptycene-based dianhydride (PPDAn) and a pentiptycene imide-containing diamine (PPImDA)] and
